Why is it that a throttling device always has a valve leading to it? If in a closed system loop, a cooled gas exists right before the throttling device, shouldn't the sudden decrease in cross-sectional area reduce pressure without the valve, just as good as with it? Maybe my misunderstanding lies in the operation of the valve. 2 Thermodynamical (macro) versus micro states 2. For example, the ultimate definition of temperature is "what a thermometer reads".

Below is a list of basic devices in thermodynamics for which you should know basically what they are and what they do. 25. Keywords - Journal. Models are a simplified, empirical To understand the fundamental concepts of thermodynamics, basic principles (conservation of mass, conservation of energy, concept of entropy) and basic thermodynamics terminology (System, Property, State, Equilibrium, Process, Thermodynamics is a branch of physics that deals with heat, work, and temperature, and their relation to energy, entropy, and the physical properties of matter and radiation.
